Illustration 3.52 Flip Flop Outputs
The two operators can be selected from a long list. As a
special case, the same digital input can be used as both
Set and Reset, making it possible to use the same digital
input as start/stop. The following settings can be used to
set up the same digital input as start/stop (example given
with DI32 but is not a requirement).
